Have you ever hiked at night with a headlamp on a trail with such highly reflective blazes, especially one that's been over blazed? It can be intrusive IMHO. These types of highly reflective blazes are mostly used on trails when the trail is widely experienced under specific conditions such as rain, fog(smoke), at night, or trails that are experienced by many under snow/ice, etc They use blazes like this on snowmobile, sking, snowshoeing, and winter hiking trails. Where you live it can make sense though as long as it's not overdone.
